Efficient combined three-phase separator

Abstract

The invention discloses an efficient combined three-phase separator, which comprises a three-phase separator shell and a sloping plate installed at the side of the shell, wherein a plurality of reflection plate single bodies are alternately arranged in horizontal and vertical directions inside the three-phase separator shell, and the reflection plate single bodies are in a bucket shape with large bottom and small top. As a further improvement of the efficient combined three-phase separator, the bucket-shaped reflection plate single body is provided with a mouth part in an unfilled-corner square shape with a downward opening and air chambers at the top, the air chambers are connected in series by an air collecting pipe, a partition is arranged inside the air collecting pipe, and air inflow and outflow holes are separately formed on the upper and lower parts of the partition. The efficient combined three-phase separator provided by the invention has the advantage of high separation efficiency, good separation effect and easiness in installation.

Description

technical field [0001] The invention relates to a separation device for separating solid, gas and liquid three phases, in particular to a combined three-phase separation device. It belongs to the field of sewage treatment. Background technique [0002] The three-phase separation device is an important structure and equipment of anaerobic reactors such as UASB, EGSB, and IC. It plays a very important role in the normal operation of the sludge bed and obtaining good effluent water quality. Three-phase separation is to separate the anaerobic activated sludge (solid phase), sewage (liquid phase) and biogas (gas phase) in the tank. The anaerobic activated sludge is collected and retained in the tank to continue processing sewage, and the biogas is collected into the biogas tank as Fuel recovery, sewage is treated and separated and then flows out to the next treatment unit. [0003] The current common three-phase separation device is generally an integral type, mainly composed o...

Problems solved by technology

However, this kind of technology has not been able to solve the problem of the oversized and complicated installation of the integral three-phase separator. Even if some technologies have proposed the idea of ​​split and combined three-phase separators, they cannot be very good in practice. Good solution to the problem of low separation efficiency and incomplete separation effect

Judging from the existing technical literature, few people mention the structural improvement of the inverted V-shaped reflector. In the process of improving the three-phase separation device, ordinary technicians will replace the double-sided reflector with Triangular, quadrilateral or even polygonal shapes can easily form water flow gaps in the shell, resulting in the problem of direct current penetration of local upward water flow, which ultimately affects the separation effect. In addition, the cost of the transformation research process is relatively high, and the possibility of successful transformation is low. Therefore, the existing three-phase Although the separation device obviously has weaknesses such as low separation efficiency and difficult installation, few people are willing to improve it
